Summary
Sural nerve biopsy was performed in twenty-four diabetic patients, with clinical and electrophysiological evidence of diabetic neuropathy. Material from an autopsy case was also examined. Vessels plugged with fibrin were seen within nerve in nine cases. In three cases fibrin was observed tracking into the vessel wall and in four, older thrombus was observed in vessels. Areas of necrosis in nerve bundles were seen in two of the latter. In two patients there had been a preceding episode of intravascular coagulation. Fibrin deposition within small vessels could well play a part in damaging the diabetic nerve and a disturbance of the balance between deposition and removal by fibrinolysis could explain phasic variation in the symptoms of neuropathy.
